3d Object Model Reconstruction from 2d Images

3. The method of claim 1, wherein determining the three-dimensional position of the key point in the three-dimensional scene is further based on a focal length of a camera that captured the two-dimensional image.

4. The method of claim 1, wherein the position dependent rotation is a rotation by an angle dependent on a ratio of a two components of the three-dimensional position of the key point, wherein one of the two components is a depth component.

6. The method of claim 5, wherein projecting the positioned three-dimensional representation into a two-dimensional image plane is based at least in part on absolute depth of the key point and depths of the mesh nodes defined by the three-dimensional representation.

7. The method of claim 1, further comprising training a model using an absolute depth that is a function of the pixel size, the absolute depth being used to determine the depth of the key point.

12. The system of claim 10, wherein determining the three-dimensional position of the key point is further based on a focal length of a camera that captured the two-dimensional image.

13. The system of claim 10, wherein the position dependent rotation is a rotation by an angle dependent on a ratio of a two components of the three-dimensional position of the key point, wherein one of the two components is a depth component.

15. The system of claim 14, wherein projecting the positioned three-dimensional representation into a two-dimensional image plane is based at least in part on absolute depth of the key point and depths of the mesh nodes defined by the three-dimensional representation.

16. The system of claim 10, the operations further comprising training a model using an absolute depth that is a function of the pixel size, the absolute depth being used to determine the depth of the key point.

21. The non-transitory computer readable medium of claim 19, wherein determining the three-dimensional position of the key point is further based on a focal length of a camera that captured the two-dimensional image.
